Sarah Wayne Callies wants to clear something up for those Walking Dead fans still upset with Lori’s anger toward Rick after he killed Shane in the show’s Season 2 finale.

“I don’t think her reaction had to do with the fact that [Rick] killed Shane,” says Callies, dropping by TVLine’s Comic-Con interview suite. “The right man, I think in her mind, did walk out of that fight.” In fact, Callies offers, Lori’s horror had more to do with the fear that Rick might be turning into someone very similar to the former buddy he’d just slain.

Callies previews the “fallout” of the Lori-Rick confrontation that’s coming in The Walking Dead‘s Season 3 (premiering Oct. 14), chuckles about YouTube videos devoted to her character calling out for her son Carl, and even speculates how she’d handle it if the show’s producers ever decided it was time for her character to leave this mortal coil.
